When is the Lesser tubercle is medial profile
in an internal rotation

Would the image below need to be repeated? If so, why?
Yes, it needs to be repeated because the bladder was clipped.

refers to trauma to the upper shoulder region resulting in a partial or complete tear of the AC or coracoclavicular (CC) ligament or both ligaments.

A patient has an obvious wrist deformity and they are unable to move their arm for a lateral position. How you would perform the lateral wrist?
Perform a x-table (horizontal beam) of the wrist, with minimal patient movement.
500
What kind of projection is this?
lateral oblique for elbow
500
What should you do when a patient can't hold weights during an AC joint test?
take the test in a supine position. Have the patient hold onto gauze or a sheet with knees bent, then slowly straighten legs.
